Input/Output (I/O) is one of the fundamental aspects of computing that you have to deal with at some point during the application's development phase. Dealing with I/O presents its own challenges because I/O access is still slow. For example, reading or writing data from or to a disk involves a choreography of electronic, mechanical, and computer engineering disciplines, making the task slow in comparison to, say, reading or writing from random access memory over a high-speed bus. To minimize the impact of working with slow I/O mediums and to maximize throughput and performance, software designers have devised a variety of strategies. These strategies include, but are not limited to, vectored I/O (scatter/gather) and multiplexing I/O. These strategies can be found in use... (more)

Java Annotation Facility - A Primer

The 5.0 release of JDK introduced a slew of new features. A powerful technique that resulted from the JSR-175 recommendation is the Program Annotation Facility. It can annotate code in a standard way and automate the generation of source code or configuration files, helping cut down on boilerplate code. At the moment, the closest thing to annotating source and generating support file/co... (more)
